While respecting your expertise, with dozens of sources polluting our 
environment, it's easy for those multiple sources to obscure each 
individual source, and lead us to believe that none of them is 
contributing. AND we hear our neighbors' sources.

I strongly urge everyone to replace ALL switch-mode supplies with linear 
supplies and repeat any tests to prove that your "stuff" is not part of 
the problem. I run lots of "stuff" on small sealed lead-acid batteries 
that are float-charged from linear supplies -- everything from cable 
modems, and routers to video monitors and stuff in the home 
entertainment system -- and that helps. Yes, I stil hear trash from my 
neighbors, but that's several dB down. Every little bit helps us hear 
the weak DX. Yesterday, I worked an AF DXpedition on 160M, 7,500 miles 
away.
